<h1>Service Worker Tests</h1>
<p>Demonstrates running <tt>testharness</tt> based tests inside a service worker.
<p>The test harness should time out due to one of the tests inside the worker timing out.
<p>This test assumes that the browser supports <a href="http://www.w3.org/TR/service-workers/">ServiceWorkers</a>.
